CROSS-REFERENCE TO RELATED APPLICATION

This application is a non-provisional of, and claims the benefit and priority of, U.S. Provisional Patent Application No. 62/042,431, filed on Aug. 27, 2014. The entire contents of such application are hereby incorporated by reference.

BACKGROUND

When shooting an arrow with a bow, the shooting force can cause vibrations in the bow. The vibrations can interfere with shooting performance. An archery bow stabilizer is a known accessory used to absorb or dampen the vibrations. The bow stabilizer typically has a cylindrical body with a weighted end. The bow stabilizer attaches to the front of the bow (facing the target) and extends horizontally from the front of the bow. The weighted end can also act as a counterbalance, helping to keep the bow steady and stable during shooting. In addition, the bow stabilizer includes a dampening device mounted at the weighted end of the bow stabilizer.

Typically, the bow stabilizer bow side surfacebow front surfaceforms a 90 degree angle with an axis extending vertically through the bow riser. However, successful operation of a bow is highly specific to each individual archer and is dependent on the feel and balance of the bow in the archer's hands. For a particular archer, particular style of bow and particular style of bow stabilizer, there is an ideal angle at which the bow stabilizer extends from the bow. Attempts have been made to allow for angle adjustment, but such attempts involve mechanisms that are difficult to operate, unreliable, complex and require a relatively high manufacturing cost. As a result, the archer is unable to readily or conveniently adjust the stabilizer's angle to the archer's preference. This, negatively influences the feel of the bow for archers and generally hinders shooting performance.

The foregoing background describes some, but not necessarily all, of the problems, disadvantages and shortcomings related to bow stabilizers.

SUMMARY

An adapter for positioning an archery bow stabilizer at a customizable angle is described herein. The adapter can take one of several forms, such as a plurality of bushings, an insert configured to mate with a cavity in the bow riser, or a geared attachment.

In an embodiment, a positioning system for an archery bow stabilizer is described. The positioning system includes an insert configured to be inserted into a cavity defined by an inner surface of a bow riser. The bow riser extends along a riser axis and the cavity includes a space and a recess. The insert has an insert body defining an opening positioned on a first insert axis.

DETAILED DESCRIPTION

FIG. 1 is a plan view of a bow riser 10 which, in an embodiment, includes the handgrip portion of an archery bow. The bower riser 10 is shown as a fragment of an archery bow having upper and lower limbs, one or more pulleys and a bow string. In an embodiment, the positioning system 2 includes two forward-facing bushings 101, 102. The bushings 101, 102 are configured to be inserted into, and recessed into, a front face 11 of the bow riser 10. The bushings 101, 102 are each configured to receive an archery bow stabilizer 22 (see FIG. 3). For example, each bushing 101, 102 can be threaded to receive the stabilizer 22. In the example of FIG. 1, each bushing 101, 102 has a respective axis 12, 14, respectively, that is offset from the axis 12, 14, of the other bushing by a particular angle 16, such as, for example, 10 degrees. In other embodiments, a different offset angle is selected.

FIG. 2 is a magnified view of the positioning system 2 including its bushings 101, 102. As illustrated in this figure, each bushing 101, 102 can have a threaded surface 18, 20, respectively, for receiving, and threadably engaging with, the stabilizer 22. It is noted that while the bushings 101, 102 are illustrated here as having a threaded surface 18, 20 for receiving the stabilizer 22, any other type of fitting, such as a press or snap fit, would also be suitable.

FIG. 3 shows the positioning system 2 used to couple an archery bow stabilizer 22 to the bow riser 10. Here, the positioning system 2 includes, or is used together with, a collar or stabilizer adapter 24. The stabilizer adapter 24 has been connected to the bushing 102 to cause the stabilizer 22 to extend at an angle 16, e.g., 10 degrees, below the horizontal axis 4. For example, the stabilizer adapter 24 may have threads that engage the threads 20 of the bushing 102 to secure the stabilizer adapter 24 therein. A similar threaded connection may be used to secure the stabilizer 22 within the stabilizer adapter 24. In another embodiment, the stabilizer 22 and the stabilizer adapter 24 are monolithic. FIG. 4 is a magnified view of FIG. 3.

In an embodiment, the stabilizer 22 includes: (a) a tubular, elongated body or arm 5 extending along a stabilizer axis 6 from a bow-interface end 7 to a free end or distal end 8; (b) a vibration dampening device 9 attached or coupled to the distal end 8; and (c) one or more elements attached to or housed within the arm 5 or distal end 8 for purposes of adding weight or absorbing vibrations and shot, including, without limitation, weight members, rubber, gel or sand. The dampening device 9 acts to dampen and/or eliminate noise and bow vibration. In an embodiment, the dampening device 9 is located and configured to separate the arm 5 from the weighted, distal end 8 so that, when the bow is shot, vibration is cancelled out when it meets the dampening device 9 because the weighted distal end 8 is allowed to oscillate at a different frequency than the rest of the stabilizer 22 and bow, turning the vibration into motion that does not affect the rest of the bow.

In the embodiment of FIG. 5, the stabilizer adapter 24 has been connected to the bushing 101 to cause the stabilizer 22 to extend horizontally from the bow riser, i.e., at an angle of 0 degrees from horizontal axis 4. While the angle at which the adapter 22 extends has been described herein as relative to the horizontal axis 4, the angle can also be defined relative to riser axis 30 through which the bow riser 10 extends. In such context, the angle is specified as: (a) the angle between the axis 17 of the adapter 22 and an end, such as the upper end 26 or the lower end 28; or (b) the angle between the axis 17 of the adapter 22 and the axis 30 of the bow riser 10.

In another embodiment, illustrated by FIGS. 6-14, the positioning system 17 couples the stabilizer 22 to the bow riser 10. In this embodiment, positioning system 17 includes: (a) a removable slug or insert 32; (b) a bow interface or bow mating member 52; and (c) a collar or adapter 56. As described below, the adapter 56 has an extension, finger or fastener 54, such as a rod, screw or bolt. In this embodiment, as further illustrated by FIG. 10, the bow riser 10 has a cavity 34, such as an arc-shaped or key-shaped slot, defined by an inner surface 36 of the bow riser 10. The cavity 34 has a perimeter, much of which is circular, that defines a main space. A portion of the perimeter of the cavity 34, such as the lower perimeter, defines a recess 38. The recess 38 can be a notch, groove, channel, slot or cutout. The cavity 34 can extend side-to-side through the bow riser 10 and can also include an opening 40 in the front face 11 of the bow riser 10 in order to provide access to the cavity 34.

As illustrated in FIG. 10, the insert 32 can have a body 42 with a shape that corresponds to the shape of the cavity 34. In this example, the body 42 has a male key shape, and the cavity 34 has a female key-receiving shape. In addition, the insert 32 has a protrusion 44 extending from the insert body 42. The shape of the protrusion 44 corresponds or conforms to the shape of the recess 38. In addition, as shown in FIG. 11, the insert 32 includes an opening 46 positioned on a first insert axis 48 of the insert 32. The protrusion 44 extends from the insert body 42 along a second insert axis 50. The difference between this first insert axis 48 and second insert axis 50 defines an angle θ along which the stabilizer 22 extends. As discussed above, this angle θ can be specified relative to riser axis 30, an end of the bow riser 10, or relative to horizontal axis 4.

The bow mating member 52 is configured to couple to the stabilizer 22 to the curve-shaped or convex, bow front surface 11 via any suitable means, such as a press or snap fit or a threaded fit. The bow mating member 52 serves as a adapter between the relatively flat end 53 of the bow mating member 52 and the non-flat, non-uniform and convex shaped bow front surface 11. In an embodiment, the bow mating member 52 has a bow-facing surface 57 having a concave shape configured to mate with the convex bow front surface 11, and the bow mating member 52 has a substantially flat stabilizer-facing surface 59 configured to engage the substantially flat end 53 of the bow mating member 52. It should be understood that the bow-facing surface 57, which contacts the bow front surface 11 of the bow riser 10 when the system is assembled, has a shape that configures to the shape of the bow front surface 11 of the bow riser 10 to further stabilize the position of the stabilizer 22. As described below, the different faces 57 and 59 of the bow mating member 52 facilitate the screw-on attachment of the stabilizer 22 to the bow riser 10.

In an example, the fastener 54 extends through the bow mating member 52. For example, the fastener 54 can be coupled to the adapter 56 that couples to the stabilizer 22 and the fastener 54 extends through the bow mating member 52 to couple to the insert 32, as illustrated in FIGS. 13-14. In another example, the fastener 54 can be integral with the stabilizer 22 and can extend through the adapter 56 and/or bow mating member 52. In yet another example, the fastener 54 is integral with the bow mating member 52.

The insert 32 and bow mating member 52 form a positioning system for the stabilizer 22. In operation, the insert 32 is inserted into the cavity 34, such as via the opening 40 in the front face 11 of the bow riser 10, so that the insert body 43 is received in the cavity 34, the protrusion 44 is received in the recess 38 such that the insert 32 is held in a fixed, non-rotating position, and the opening 46 is accessible via the opening 40 in the front face 11 of the bow riser 10. The fastener 54 is inserted through the bow mating member 52 into the opening 46 of the insert 32. The fastener 54 is tightened, such as through a threaded connection, so that the contact surface 57 of the bow mating member 52 tightly contacts the bow front surface 11 of the bow riser 10 and the stabilizer 22 tightly contacts the bow mating member 52.

When the stabilizer 22 is coupled to the insert 32, the stabilizer 22 extends at the angle θ defined by the first 48 and second 50 axis of the insert 32. As discussed above, this angle θ is determined by the position of the protrusion 44 relative to the opening 46 in the insert 32.

The user may select the angle at which the stabilizer 22 extends simply by selecting an insert 32 having the desired preset angle. The insert 32 can have an angle indicator, such as a color or a label, that indicates the angle of the insert 32. Various inserts 32 may be manufactured with different, predetermined angles for a user to interchange inserts 32 for different angle options. In an example, a bow stabilizer angle adjustment kit may include several inserts 32, each having a different angle.

In another embodiment, illustrated by FIGS. 15-22, a bow riser 10 includes a front face 11 positionable to face toward a shooting target, a bow back surface 13 opposite the front face 11, and a plurality of bow side surfaces 15. As illustrated in FIG. 19, at least one bow side surface 15 has a bow side recess 60. As illustrated in FIG. 20, the perimeter of the bow side recess 60 is bound by a rotation stop wall 63. In an example, the bow side recess 60 can include a cavity 62. The cavity 62 can extend through the bow riser 10, or each bow side recess 60 can include a cavity 62 that does not extend fully through the bow riser 10.

A coupler 64 is configured to couple the stabilizer 22 to the bow riser 10. The coupler 64 has a bow coupler end 66 that has at least one mount 68. In an example, the coupler 64 includes two mounts 68, which extend parallel to each other in a U-shaped or fork-shaped fashion. Each mount 68 can include a through-hole 69 The mount(s) 68 is configured to be at least partially inserted into the bow side recess 60. The mount(s) 68 has a mount perimeter that is smaller than the perimeter of the bow side recess 60. A main fastener 70 couples the mount(s) 68 to the bow riser 10. The main fastener 70 can be any suitable type of fastener. For example, the main fastener 70 can be a pin or rod that extends through the cavity 62 and the through hole 69. In another example, the cavity(s) 62 can have a threaded surface and the fastener 70 can be a screw or bolt that extends through the cavity 62 and the through-holes 69 and pull the mounts 68 together to form a pinch, sandwiching hold or clamping force around the bow riser 10. In another example, the cavities 62 can be blind tap holes, and the main fastener 70 can be a shoulder bolt and a socket. In a further example, the main fastener 70 can be a pin that extends through the cavity 62 and the through holes 69 as a rotational point and the bow riser 10 can include a secondary tap hole offset from the holes 69 configured to receive a secondary fastener (e.g., a threaded set screw) to help lock the coupler 64 in place.

The perimeter of the bow side recess 60 can be larger than the perimeter of the mount 68. Because of this sizing difference, the mount 68 can be rotated within the bow side recess 60 a particular range, such as within a 10 degree range. In an example, a riser contact surface 72 can have a shape that corresponds to the shape of the front 11 of the bow riser to facilitate this rotation. The rotation stop wall 63 serves to restrict the rotational adjustability of the mount 68. For example, if a user were to rotate the mount 68 too far upward to a maximum upward position, the mount would come into physical contact with, and be stopped by, the rotation stop wall 63. In any maximum upward or maximum downward position, the rotation stop wall 63 also provides support to the stabilizer 22.

The position of the mount 68 is adjustable within the adjustment range defined by the rotational stop wall 62. Within this range, the mount 68 can be locked as discussed above using one or more fasteners, such as fastener 70. Referring to FIG. 16, once set to a desired position, the position of the mount 68 within the bow side recess 60 determines an angle θ at which the stabilizer 22 coupled to the coupler 64 extends relative to the riser axis 30. The coupler 64 optionally can include a brace section 74 on at least one surface of the coupler 64 that is configured to contact the bow riser 10 when the coupler 64 is positioned at desired angle. This brace section 74 provides further stability to coupler 64 when the coupler is positioned at this angle. In an example, the coupler 64 can include a first brace section 74 on a first surface, such as a bottom surface, of the coupler 64 and a second brace section on a second surface, such as a top surface, of the coupler, each of the first and second brace sections configured to contact the bow riser 10 when the coupler 64 is positioned at different angles.

The collar 76, described above, can be coupled to the stabilizer 22. The collar 76 can be integral with the stabilizer 22, or the collar 76 can be removably coupled to the stabilizer 22. The collar 76 can include a fastener 78. Alternatively, the fastener 78 can be integral with the stabilizer 22 and inserted through the collar 76. The fastener 78 is configured to be received in a cavity 80 in the stabilizer contact surface 82 of the coupler. When the stabilizer 22 is coupled to the bow riser 10 via the coupler 64, the stabilizer 22 extends at an angle θ defined by the position of the mount(s) 68 in the bow side recess(s) 60.

In another embodiment, the bow side surface(s) (not shown) of the bow riser 10 does not include a recess. In this embodiment, the coupler includes at least one mount having a through hole. A fastener can extend through the through hole to couple the at least one mount to such a non-recessed side surface. The at least one mount can rotate about the fastener in order to extend the coupler and the attached stabilizer at a selected angle. When the coupler and the stabilizer are positioned at the selected angle, the fastener can be positioned to maintain the at least one mount at the selected angle, such that the stabilizer extends at the desired angle.

In another embodiment, FIGS. 23-24 depict an embodiment of a positioning system 1206 having a plurality of gears 1200 and a stabilizer adapter 1203. In an embodiment, the adapter 1203 includes a matching set of gears 1201 and a circular insert 1202 that fits into an arc slot 1204. The gears 1201 protrude in a direction that is orthogonal to the axis of rotation of the circular insert 1202. In use, the archer inserts the circular insert 1202 into the arc slot 1204 while aligning the gears 1200, 1201 so as to produce a desired angle θ. Due to the presence of the plurality of gears 1200, a different angle θ may be formed for each tooth. For example, in FIG. 23, an angle θ of about 0° is shown.
